Border mires
Butterburn Flow is the largest of 58 mires straddling the border between Cumbria and Northumberland, collectively known as the Border Mires.
Butterburn is bounded on two sides by the River Irthing which itself forms the border between the two counties.
During the 20th century, much of the area was planted with conifers by the Forestry Commission, forming the Kielder Forest, the largest forest in England at 50,000 hectares.
The peat bogs within the area were generally avoided although some planting and drainage did occur on the edges of the bogs and some sites were drained in preparation for afforestation.
What makes Butterburn Flow so special?
Butterburn Flow is a blanket bog, meaning that it lies over the landscape like a wet blanket. It receives moisture from groundwater as well as from rainfall.
Surprisingly, it’s relatively intact with a high water table as there’s been little artificial drainage in the past.
As a result, peat is still actively growing and an abundance of Sphagnum moss, which forms extensive lawns and hummocks, known as patterned mire thrives in this wet environment.
Keeping it special
Butterburn Flow is owned by the Forestry Commission and managed by Northumberland Wildlife Trust.
